Finally I got my ZX81 from Danish distributor to work again with Andy Rea's new ULA.

I found a second cut on the pcb from the destructive removal of the old ULA. So now there's 2 wires on the bottom of the pcb, and it works great, and a new transistor has been inserted where one was removed in the debug fase.

You can even see the inverse screen created by Andy's custom firmware.

Now off to bed. Tomorrow will bring new adventures with enabling of the ULA's M1NOT feature and maybe enabling of composite output.

Thanks again to everyone here helping me to resurrect this old friend.
